16.vue-cli跨域,swiper,移动端项目

解决跨域：

1、后台 cors cnpm i -S cors

2、前端 jsonp

3、代理 webpack: myvue\config\index.js 找 proxyTable

proxyTable: {
  "/anhao": {
    target: "http://localhost:3000",
    changeOrigin: true,
    pathRewrite: {
//需要rewrite重写的, 如果在服务器端做了处理则可以不要这段
      "^/anhao": ""
    }
  }
},

vue插件:

axios vue-axios vue2-animate vuex swiper

cnpm i -S axios vue2-animate vuex swiper

vuex swiper //轮播特效copy

---

移动端布局：rem

rem:  r---> html em
html{font-size:100px;}
标准的字体大小 100        当前的字体的大小 rem?
-------------------  = -------------------
表示视图的宽度 750        当前的视图的宽度 document.documentElement.clientWidth
320px 640px  750px 1250px
rem?= 100/750*clientWidth = clientWidth/(7.5|3.75) + "px";

---

<transition>
	<div v-show="isShow"></div>
</transition>

---

vue--->vuex

1、直接调用mutations ----> commit

2、直接调用actions ---> dispatch
